Describe the bug

The Files_Sharing app is required in order to attach a file to a card. This is even if no sharing is required.

To Reproduce

1. Disable Files_Sharing app
2. Go to deck, try to attach file
3. Fails with error (more info in logs)

Expected behavior Should be possible to attach a (non-shared) file to a Deck card. At least, better behaviour would be to show a more useful error message: "Files_Sharing app must be enabled to attach a file"

I have noticed that the file actually saves in the Deck folder, it just does not appear as an attachment on the card.
